Half-Life 2

As you all know, there was a recent update to Half- Life 2, Half-Life 2: Episode 1, Half- Life 2: Episode 2, and Portal, making dual stick controllers the primary controller layout. However, I plugged in my Logitech RumblePad 2 USB controller, which is basically a PS2 controller with a USB, and, with some messing with keybindings, I got everything to work EXCEPT for looking up and down.Now, I have tried the same thing BEFORE the update, and still had the same problem.This controller works fine for every game I have tried it on, except for Source games.I also have a Saitek P880, which works just as well as my RumblePad 2 USB, with the exeption of less buttons and a few bugs in some games, and a Saitek P750, which doesn't work at all, so I don't know why I decided to mention that.I do have all the drivers installed for these controllers. Does anyone know how to get it to work?
